COMBINATION PLUMBTIiI N E Ann LEVEL.

Application filed nine v4,

Thisinvention relates generally to plumblines and levels, and has moreparticular reference to a novel type of combination plumb-bob and level.

The invention has for an object the provision of an improved plumb-boband level which will consist of an integral unit, facilitating use foreither a plumb-bob, or level, andat the same time eliminating possibleinjury of the level, due to rough handling or dropping of the plumb-bob.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing,

and to the appended claims in which the various novel features of theinvention are more particularly set forth.

Referring to the accompanying drawing forming a material part of thisdisclosure Fig. 1 is a perspective view of the invention device.

Fig. 2 is a side elevational view of the same, with a portion brokenaway disclosing the interior parts.

Fig. 3 is a similar view as that shown in Fig. 2, but of a modified formof the invention.

Fig. 4 is a side elevational view of a further modified form of theinvention, with a portion broken away disclosing the interior parts.

Fig. 5 is a vertical transverse sectional view taken on the line 55 ofFig. 4.

The reference numeral 10 indicates a portion of the plumb-line attachedto the plumbbob 11-, as at 12. The plumb-bob is formed with a centralportion 13, of any desirable shape, an integral front pointed portion14, and a rear portion 15, secured to the central portion 13, by meansof a projection 15 from the member 15, engaging an aperture 16 in themember-13. The member 13 is formed with agroove 13, and a level 17 ofcustomary construction is housed in the I member 13 so as to be readablefrom the groove 13. Preferably cement 18 is used to fasten the level 17in the proper position.

In the modification illustrated in Fig. 3, the level 17 is made ofglass, and has a surrounding casing 19 of rubber, or similar shockabsorbing material. Should the plumb-bob he accidentally dropped, dangerof the level 17. breaking is eliminated, due to the casing 19.

In the modification shown in Figs. 4 and 5,

a slidable member 20 isengaged to the central member 13, and slidablyheld by the depending portions 21. A door 22 to close the groove 18*, ispivotally secured to the slidable member 20, as at 23. The door 22 isformed with a cam face 22*, engaging the face of the groove 13 so thatupon sliding the member 20 rearwards, the door 22 is wedged open,allowing the level 17 to be used. The door 22 is normally urged toclosed position by the action of spring 24 acting between members 20 and22. When the plumb-bob is used, the door 22 in its closed position, actsto perfectly balance the ho Vhile I have illustrated and described myinvention with some degree of particularity, I realize that in practicevarious alterations therein maybe made. I therefore reserve the rightand privilege of changing the form of the details of construction orother-- wise altering the arrangement of the cone PATENT lop-me. j

lated parts without departing-from the spirit or the scope of theappended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is l. A level of the classdescribed comprising a body portion of hexagonal cross-section having acentral longitudinal opening therein extending from one end thereof andterminating in spaced relation to the other end thereof, a level vialadapted to be inserted in said opening through the first men tioned endof said body member, a plug comprising a projection having an openingtherein for receiving a cord to adapt said level to be used as a plumbbob, said plug being adapted to be inserted in the outer end of saidcentral longitudinal opening after insertion of said level vial forretaining said vial in a proper position, said body portion having arecess therein formed by the removal of a semi-cylindrical sectionthereof for permitting observation of said vial, a

hinge mounted on said body portion adjacent iection having an openingtherein for receiving a cord to adapt said level to be employed as aplumb bob, disposed in the end of said opening adapted to retain saidvial therein, a pointed projection on the other end of said level, saidbody portion having an outer recess therein for permitting observationof said level vial, and a pivotally mounted lug adapted tobe disposed insaid recess for protecting said level vial, the outer surface of saidlug being adapted to conform with the surfaces of the body portion ofsaid recess in flush relation thereto and the material of said lug beingof suitable mass to balance said level body for causing the center ofmass ofsaid'level to fall in a straight line HENRY MURRAY.
